Abstract

The purpose of the research is to determine the quality of the development of realistic mathematics module based on exe- learning materials in the form of algebra to enhance mathematics comprehension of the seventh-grade students of Junior High School from the aspect of validity, practicality, and
effectiveness.

This research belongs to research and development. Research and development are conducted in accordance with the procedures of R & D from Borg & Gall through some modification consists of the following steps: (1) a preliminary study and data collection, (2) the preparation of the module, (3) the validation of the module continued by revision, (4) focus group discussion followed by the revision of the results, (5) the initial field trials, (6) the improvement of the initial field trial results, (7) the implementation of the test field, (8) the revision of the implementation of the test field.

Algebra generated module has been valid because it has fulfiled two types of validity, namely: content validity and construct validity. Content validity is used because the process of development has been adjusted by the procedures of R & D from Borg & Gall. While observing construct validity where assessment is based on the correlation among the various components which arrange the product has been validated by two experts each on matter and media. The developed module in this research has met the practical criteria based on the students’ responses and obtained good score. This module is
also effective because it is based on the value of the t (4.834) > t table (2.042) which means that the result of mathematics comprehension for the experimental class is different from those in the control group. From three criteria above, the use of exe-learning for the module has fulfiled the criteria of validity, practicality, and effectiveness.
